Foot step energy generator

  1. 1. INTRODUCTION For an alternate method to generate electricity there are number of methods by which electricity can be produced, out if such methods footstep energy generation can be an effective method to generate electricity. Walking is the most common activity in human life. When a person walks, he loses energy to the road surface in the form of impact, vibration, sound etc, due to the transfer of his weight on to the road surface, through foot falls on the ground during every step. This energy can be tapped and converted in the usable form such as in electrical form. This device, if embedded in the footpath, can convert foot impact energy into electrical form.
  2. 2. CONVENTIONAL AND NONCONVENTIONAL ENERGY SOURCES Energy which is produced by such methods which are quiet familiar to a country is called conventional sources for that country where as the sources which are not familier to a country are called non conventional energy sources for that country
  3. 3. The sources of energy which have been in use for a long time, e.g., coal, petroleum, natural gas and water power. They are exhaust able except water. They cause pollution when used, as they emit smoke and ash. They are very expensive to be maintained, stored and transmitted as they are carried over long distance through transmission grid and lines. Conventional Sources of Energy
  4. 4. Non-Conventional Sources of Energy The resources which are yet in the process of development over the past few years. It includes solar, wind, tidal, biogas, and biomass, geothermal. They are inexhaustible. They are generally pollution free. Less expensive due to local use and easy to maintain.
  5. 5. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India and China where the roads, railway stations, bus stands, temples, etc. are all over crowded and millions of people move around the clock. This whole human/bioenergy being wasted if can be made possible for utilization it will be great invention and crowd energy farms will be very useful energy sources in crowded countries. Walking across a "Crowd Farm," floor, then ,will be a fun for idle people who can improve their health by exercising in such farms with earning. The electrical energy generated at such farms will be useful for near by applications. NEED FOR THE SYSTEM
  6. 6. BASIC PRINCIPLE The downward movement of the plate results in rotation of the shaft of an electrical alternator, fitted in the device, to produce electrical energy. The top plate reverts back to its original position due to negating springs provided in the device

  9. 9. MODEL OF FOOTSTEP ENERGY GENERATION
  10. 10. WORKING PRINCIPLE The complete diagram of the foot step power generation is given above. The pushing power is converted into electrical energy by proper driving arrangement. The rack & pinion, spring arrangement is fixed at the pavement. The spring is used to return the inclined step in same position by releasing the load. The larger sprocket also coupled with the pinion shaft, so that it is running the same speed of pinion.
  11. 11. The larger sprocket is coupled to the small cycle sprocket with the help of chain (cycle). This larger sprocket is used to transfer the rotation force to the smaller sprocket. The smaller sprocket is running same direction for the forward and reverse direction of rotational movement of the larger sprocket. This action locks like a cycle pedaling action. The fly wheel and gear wheel is also coupled to the smaller sprocket shaft. The flywheel is used to increase the rpm of the smaller sprocket shaft.
  12. 12. The pinion shaft is connected to the supported by end bearings as shown in fig. The gear wheel is coupled to the generator shaft with the help of another gear wheel. The generator is used here, is permanent magnet D.C generator. The generated voltage is 12Volt D.C. This D.C voltage is stored to the Lead-acid 12 Volt battery. The battery is connected to the inverter. This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This 230 Volt A.C voltage is used to activate the light, fan and etc. By increasing the capacity of battery and inverter circuit, the power rating is increased
  13. 13. FOOTSTEP ARRANGEMENT
  14. 14. RACK AND PINION ARRANGEMENT A rack and pinion is a type of linear actuator that comprises a pair of which convert gears rotational motion into linear motion. The circular pinion engages teeth on a linear "gear“ bar–the rack. Rotational motion applied to the pinion will cause the rack to move to the side, up to the limit of its travel.
  15. 15. CHAIN SPROCKET This larger sprocket is used to transfer the rotation force to the smaller sprocket. The smaller sprocket is running same direction for the forward and reverse direction of rotational movement of the larger sprocket. This action locks like a cycle pedaling action.
  16. 16. FLY WHEEL The fly wheel and gear wheel is also coupled to the smaller sprocket shaft. The flywheel is used to increase the rpm of the smaller sprocket shaft. The gear wheel is coupled to the generator shaft with the help of another gear wheel.

  18. 18. APPLICATIONS Foot step generated power can be used for agricultural applications. The generated power can be used for home applications. It can be used in street-lightening. Foot step power generation can be used in emergency power failure situations. Metros, Rural Applications It can be used as a source for both A.C and D.C applications
  19. 19. APPLICATION IN STREET LIGHTNING
  20. 20. ADVANTAGES Power generation is simply walking on the step Power also generated by running or exercising on the step. No need fuel input This is a Non-conventional system Battery is used to store the generated power
  21. 21. DISADVANTAGES Only applicable for the particular place. Mechanical moving parts is high Initial cost of this arrangement is high. Care should be taken for batteries
